Subject: [RFC PATCH 1/9] keys: Invalidate used request_key authentication keys
Date: Thu, 14 Feb 2019 16:56:50 +0000	[thread overview]
Message-ID: <155016341076.11489.17906138075234365532.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <155016339876.11489.901851271827069026.stgit@warthog.procyon.org.uk>

Invalidate used request_key authentication keys rather than revoking them
so that they get cleaned up immediately rather than potentially hanging
around.  There doesn't seem any need to keep the revoked keys around.

Signed-off-by: David Howells <dhowells@redhat.com>
